Description
PROCESS FOR PREPARING AND COMPOSITIONS OF MACROSPHERE
FORMULATIONS
FIELD OF THE INVENTION
[0001] There is provided herein an aqueous product and a process for preparing the same where the aqueous product has visible, discrete, and stabilized droplets, and where the aqueous product comprises: (i) droplets of an anhydrous composition comprising an oil and one or more anhydrous rheological modifying agents for rheological, visual, and/or sensorial adjustment; and (ii) an aqueous medium comprising water and one or more alkali swellable aqueous thickening agents.
BACKGROUND
[0002] The varied and unique properties of various oils create a strong need to include them in aqueous-based compositions. For example, oils such as silicone oils, fluids and gums, mineral oils, and water-insoluble organic esters such as isopropyl palmitate and isopropyl myristate, are useful in cosmetic formulations for the skin and hair. In these compositions, the lubricity properties of the oil can impart conditioning action for the user. However, oils are generally immiscible in water making it very difficult to prepare a stable aqueous dispersion that does not quickly separate into phases of oil and water.
[0003] To solve the problem of providing effective dispersibility of such materials in water, it has generally been necessary to include a surfactant in aqueous cosmetic compositions that also contain a cosmetically-active oil. The surfactant works to maintain dispersed droplets of the oil in the aqueous solution. However, the use of surfactants increases the cost of the product and may affect the quality of the composition. In addition, even with a surfactant present, the stability of the dispersion is often not satisfactory.
[0004] An alternative approach is to form macroscopic capsules of an oil by in situ aqueous polymerization of oil soluble monomers. For example, Brynko, in U. S. Pat. 2,969,330 and U. S. Pat. 2,969,331 , describe the preparation of pressure- rupturable capsules of a chlorinated diphenyl oil in water by dissolving styrene, or an acrylate or vinyl acetate monomer, in the oil, dispersing the monomer-containing oil in water with the aid of an emulsifier to form droplets, and polymerizing the
monomer to form an encapsulating wall of solid polymer material around each droplet of oil. Berg, in J. Microencapsulation (1989) 6, No. 3, 327-337, also described a process for the microencapsulation of emulsified oil droplets by in situ vinyl polymerization. De Luca, in U.S. Pat. 4,741 ,872, described the preparation of biodegradable microspheres having a three-dimensional network in which biologically active macromolecular agents were physically entrapped therein. Kopolow, in U.S. Pat. 5,073,296, describes a method for preparing discrete microdroplets of an oil stabilized by in situ polymerization of a water-soluble vinyl monomer. However, each of these approaches has its problems and the stability of their resulting dispersions is still often not satisfactory.
[0005] Accordingly, it is an object of this invention to provide an aqueous product comprising visible, discrete, and stabilized droplets of oil and processes of making the same.
SUMMARY
[0006] The disclosed technology provides an aqueous product and a process for preparing the same. The aqueous product has visible, discrete, and stabilized droplets, and where the aqueous product comprises: (i) droplets of an anhydrous composition comprising an oil and one or more anhydrous rheological modifying agents for rheological, visual, and/or sensorial adjustment; and (ii) an aqueous medium comprising water and one or more alkali swellable aqueous thickening agents.
[0007] The disclosed technology includes compositions and methods of making such compositions that, in some embodiments, may described as visible macro- spheres formulations containing anhydrous or pre-emulsified droplets suspended in an emulsifier-free, partially neutralized acrylic-based aqueous system. Additional color, pigment, glitters, and/or fragrances , and/or anhydrous compatible active ingredients may be added into the composition to enhance the visual effects and the functional performance from the ingredients above. Other than controlling the size of these suspended oil droplets by mechanical shearing and apparatus, the size and the hardness of these droplets may be altered by including anhydrous rheology modifiers, emulsifiers, or higher melting waxes in the compositions and the rheology modifier in aqueous phase. The macro-spheres dispersion may be thickened by neutralization or in conjunction with additional rheology modifying agent. The macro-spheres
compositions may be advantageously applied to both leave-on and rinse-off skin care, color cosmetic, and sun protection applications such as serum, lotion, cream, facial cleanser, alphabetic cream, lip gloss, make-up remover, body wash, shampoo, conditioner and liquid detergent with appealing aesthetics and the functional performance from the ingredients containing in the anhydrous composition. The mechanical processing, ingredient selection, and order of addition of the components are essential to make the visually appealing anhydrous oil or pre-emulsified droplets in suspension (beads). The disclosed technology includes a process for dispersing the droplets in the pre-neutralized acrylate homopolymer aqueous solution under the specific conditions, which may include a pH 4.0 ± 1.0 and viscosity < 3,000 cps, or even < 1,000 cps. The rheology and surface tension of the macro-spheres may be adjusted to desired levels by adding anhydrous oil thickener, emulsifiers, waxes, or any combination thereof in order to achieve the desired droplet size (both macro and micro), hardness, and sensory properties.

Other exemplary crosslinkers are selected from allyl ethers of sucrose and allyl ethers of pentaerythritol,
and mixtures thereof. These polymers are more fully described in U.S. Patent No. 5,087,445; U.S. Patent No. 4,509,949; and U.S. Patent No. 2,798,053 herein incorporated by reference.

In one aspect, the monomers can be polymerized in the presence of a steric stabilizer such as disclosed in U.S. Patent No. 5,288,814, which is herein incorporated by reference. Some of the forgoing polymers are designated under INCI nomenclature as Acrylates/C 10-30 Alkyl Acrylate Crosspolymer and are commercially available under the trade names Carbopol® 1342 and 1382, Carbopol® Ultrez 20 and 21, Carbopol® ETD 2020 and Pemulen® TR-1 and TR-2 from Lubrizol Advanced Materials, Inc.
[0045] In another aspect, the auxiliary rheology modifier can be a crosslinked, linear poly(vinyl amide/acrylic acid) copolymer as disclosed in U. S. Patent No. 7,205,271, the disclosure of which is herein incorporated by reference.
[0046] Another class of optional synthetic rheology modifiers and thickeners suitable for use in the present invention includes the hydrophobically modified ASTs, commonly referred to as hydrophobically modified alkali-swellable and alkali-soluble emulsion (HASE) polymers. Typical HASE polymers are free radical addition polymers polymerized from pH sensitive or hydrophilic monomers (e.g., acrylic acid and/or methacrylic acid), hydrophobic monomers (e.g., C 1-C30 alkyl esters of acrylic acid and/or methacrylic acid, acrylonitrile, styrene), an "associative monomer", and an optional crosslinking monomer. The associative monomer comprises an ethylenically unsaturated polymerizable end group, a non-ionic hydrophilic midsection that is terminated by a hydrophobic end group. The non-ionic hydrophilic midsection comprises a polyoxyalkylene group, e.g., polyethylene oxide, polypropylene oxide, or
mixtures of polyethylene oxide/polypropylene oxide segments. The terminal hydrophobic end group is typically a C8-C40 aliphatic moiety. Exemplary aliphatic moieties are selected from linear and branched alkyl substituents, linear and branched alkenyl substituents, carbocyclic substituents, aryl substituents, aralkyl substituents, arylalkyl substituents, and alkylaryl substituents. In one aspect, associative monomers can be prepared by the condensation (e.g., esterification or etherification) of a polyethoxylated and/or polypropoxylated aliphatic alcohol (typically containing a branched or unbranched C8-C40 aliphatic moiety) with an ethylenically unsaturated monomer containing a carboxylic acid group (e.g., acrylic acid, methacrylic acid), an unsaturated cyclic anhydride monomer (e.g., maleic anhydride, itaconic anhydride, citraconic anhydride), a monoethylenically unsaturated monoisocyanate (e.g., α,α- dimethyl-m-isopropenyl benzyl isocyanate) or an ethylenically unsaturated monomer containing a hydroxyl group (e.g., vinyl alcohol, allyl alcohol). Polyethoxylated and/or polypropoxylated aliphatic alcohols are ethylene oxide and/or propylene oxide adducts of a monoalcohol containing the C8-C40 aliphatic moiety. Non-limiting examples of alcohols containing a C8-C40 aliphatic moiety are capryl alcohol, iso-octyl alcohol (2- ethyl hexanol), pelargonic alcohol (1-nonanol), decyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, cetyl alcohol, cetearyl alcohol (mixture of C16 C 18 monoalcohols), stearyl alcohol, isostearyl alcohol, elaidyl alcohol, oleyl alcohol, arachidyl alcohol, behenyl alcohol, lignoceryl alcohol, ceryl alcohol, montanyl alcohol, melissyl, lacceryl alcohol, geddyl alcohol, and C2-C20 alkyl substituted phenols (e.g., nonyl phenol), and the like.

EXAMPLES
[0074] The technology described herein may be better understood with reference to the following non-limiting examples.
[0075] A series of examples are prepared using the following procedure: (1) an aqueous medium is prepared by combining, in a suitable vessel equipped with a mixed, water and the alkali swellable aqueous thickening agents. The thickening agent is allowed to completely self-wet and then the composition is mixed using a paddle blade at about 500 rpm. (2) The rest of the components for the aqueous medium (identified as Part A in the table below) are added to the mixing vessel and the composition is mixed gently until the resulting aqueous medium is homogeneous. (3) When present, a neutralizing agent (identified as PART B in the table below) is added to the aqueous medium to partially neutralize batch, here by adjusting the aqueous medium to a pH of about 3.5-3.6, within continued gentle mixing. (4) In a separate vessel, mix all the components of the anhydrous composition (identified as
PART C in the table below) adding the anhydrous rheological modifying agent last, and mix until homogeneous. Begin heating the oil phase to about 105°C and not above 1 10°C. Continue mixing until the anhydrous rheological modifying agent is solubilized, typically about 45 to 60 minutes, resulting in the anhydrous composition. (5) Add the anhydrous composition to the aqueous medium, mixing the combined mixture at less than 300 rpm. (6) Add the neutralizing agent to the batch with less than 300 rpm mixing to fully neutralize and suspend oil droplets. Once desired visual effect is achieved immediately turn off the mixer.
